They live in extreme environmental conditions.
Answer:
14mph
Explanation:
270 minutes = 4 hr and 1/2hr
63 miles = 63/4.5 = 14 miles per hour
Making the speed 14mph
Equation = h = 4.5
(4h x 4h ) + (1 x 311/100) = 60
= 4h x 4h +( 1 x 311/100) =60
= 16h^2 + (1 x 311/100) =60
= 256h + (1 x 311/100) =60
= 256h + 14 = 60
= 270h = 60
= h = 4.5
Answer:
Explanation:
Using freezing point depression formula,
ΔTemp.f = Kf * b * i
Where,
ΔTemp.f = temp.f(pure solvent) - temp.f(solution)
b = molality
i = van't Hoff factor
Kf = cryoscopic constant
= 1.86°C/m for water
= (0 - (-5.58))/1.86
= 3.00 mol/kg
Assume 1 kg of water(solvent)
= (3.00 x 1)
= 3.00 mol.
Answer:
The most acidic solution had a pH of 3.27.
Explanation:
In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.
If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.
Conversely, the least acidic one had a pH of 3.88.
